Compton
=======

**This is a development branch, bug to be expected**

This is forked from the original Compton because that seems to have become unmaintained.

The current battle plan of this fork is to refactor it to make the code _possible_ to maintain, so potential contributors won't be scared away when they take a look at the code.

We also try to fix bugs.

The original README can be found [here](README_orig.md)

## Call for testers

### `--experimental-backends`

This flag enables the refactored/partially rewritten backends.

Currently new backends features better vsync with the xrender backend, improved input lag with the glx backend (for non-NVIDIA users). The performance should be on par with the old backends.

New backend features will only be implemented on the new backends from now on, and the old backends will eventually be phased out after the new backends stabilizes.

To test the new backends, add the `--experimental-backends` flag to the command line you used to run compton. This flag is not available from the configuration file.

To report issues with the new backends, please state explicitly you are using the new backends in your report.

## Change Log

See [Releases](https://github.com/yshui/compton/releases)

## Build

### Dependencies

Assuming you already have all the usual building tools installed (e.g. gcc, meson, ninja, etc.), you still need:

* libx11
* libx11-xcb
* libXext
* xproto
* xcb
* xcb-damage
* xcb-xfixes
* xcb-shape
* xcb-renderutil
* xcb-render
* xcb-randr
* xcb-composite
* xcb-image
* xcb-present
* xcb-xinerama
* pixman
* libdbus (optional, disable with the `-Ddbus=false` meson configure flag)
* libconfig (optional, disable with the `-Dconfig_file=false` meson configure flag)
* libxdg-basedir (optional, disable with the `-Dconfig_file=false` meson configure flag)
* libGL (optional, disable with the `-Dopengl=false` meson configure flag)
* libpcre (optional, disable with the `-Dregex=false` meson configure flag)
* libev
* uthash

To build the documents, you need `asciidoc`

### To build

```bash
$ meson --buildtype=release . build
$ ninja -C build
```

Built binary can be found in `build/src`

If you have libraries and/or headers installed at non-default location (e.g. under `/usr/local/`), you might need to tell meson about them, since meson doesn't look for dependencies there by default.

You can do that by setting the `CPPFLAGS` and `LDFLAGS` environment variables when running `meson`. Like this:

```bash
$ LDFLAGS="-L/path/to/libraries" CPPFLAGS="-I/path/to/headers" meson --buildtype=release . build

```

As an example, on FreeBSD, you might have to run meson with:
```bash
$ LDFLAGS="-L/usr/local/include" CPPFLAGS="-I/usr/local/include" meson --buildtype=release . build
$ ninja -C build
```

### To install

``` bash
$ ninja -C build install
```

Default install prefix is `/usr/local`, you can change it with `meson configure -Dprefix=<path> build`

## How to Contribute
